Why does Windows not use a windows style or new windows style but instead use "fusion"?

If in light mode, does the application style ever get set directly to "fusion" in our main.cpp?

If so, that style should be passed through into CaretStyle as app.style() for use with QProxyStyle.

Perhaps we need to reorganize main.cpp to explicitly set style first before passing it through any QProxyStyles?

Also, the macStyle makes dark-light theming work more fully than fusion. Perhaps a Windows specific style would do the same for Windows leaving the hard coded dark mode changes only used by Linux?

Does using a Windows style on windows and Qt allow auto dark-light theme switches without having to restart Sigil work like it does for Qt and macOS with the macOS style?
